How to play
The map starts unlabelled. For each era, select a region and assign the realm that controlled it, then switch to the next age and do it again. Part of the challenge is reading how the borders redraw between eras. Complete every era for the full score.
Click a region on the map to select it
Choose its controlling realm from the answer palette
Switch eras to label the same map at different points in time
Use Check to score the era and Clear Era to start it over
Controls
Desktop: click a region, click a label, use the era tabs and the Hint/Check buttons
Phone & tablet: tap regions, labels and era tabs
Tips & strategy
Anchor on the realms you know first, then deduce neighbours from the borders around them
Compare eras, a region that changed hands is exactly the kind of border the game rewards spotting
Hints help on tough regions; Easy, Medium and Hard change how many realms share the map
